LOCK.

Specicaton of Letters Patent.

Patented Oct. 17, 1916.

Application filed April 15, 1914. Serial No.832,116.

To all whom t may concern Be it known that I, FRANK J. Rowsn, a citizen of the United States, residing at No. 453 Cottage street, Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Locks, of which the following is a specification.

My invention is an automatic closure for locks and particularly for a coin-controlled locking mechanism such, for example, as that disclosed in Letters Patent of the United States, No. 1,043,033, issued to me, the said Frank J. Rowse, on October 29, 1912, but its use is not limited to that pare ticular device for it can be used advantageously in connection with other devices whether coin-controlled or not.

The purposes of my invention are to provide an automatically locking closure for an auxiliary opening into the lock, such as the sight or reading opening through which may be read the counter that records the number of times the device has been coinoperated; to provide that access to the in In the accompanying drawings like reference numerals indicate like parts.

Figure 1 is a perspective view of the upper portion of a lock-box or case of a coincontrolled locking mechanism wherein my improved supplementary controlling device and coperating parts are located. Fig.- 2 is a top plan view'of the same device and parts shown in position within the lock-box or case, as seen at a section on the line 'if-gj, of Fig. 1. Fig. 3 is a front elevation of the supplementary-controlling device and its associated parts. Fig. 4 is a rear elevation of the front plate or casting ofthe box or case, with a portion of an operating lever of the coin-controlled mechanism shown in elevation. Fig. 5 is a side elevation of the cylinder of the lock and certain associated parts. Fig. 6 is a sideI elevation of the key for said lock. Fig. 7 is a top plan view of the detachable plate 2O which supports the supplemental device and its conjoined parts, in position within the case. Fig. 8 is a front elevation of the detachable plate showing the rocker-arm 32, which, when actuated by the coin-mechanism, operates the counter and it also shows the means for preventing the withdrawal of the key from its position in the lock when turned from its entering position, as hereinafter described.

In the drawings, like reference` characters indicate like parts. v

The upper portion of the case or lock-box isl shown in Fig. 1, comprising the front 1, the top 2 and the side. 3.V The opposite side 4 is seen in Figs. 2 and 4. Through the front 1 is an aperture or slot 5 for the insertion of the coin, by which (in `connection with associated parts) the principal bolt controlling mechanism within the case is operated. Said principal bolt controlling mechanism is not shown in the drawings, except a lever thereof marked 18 and hereinafter described. There is a rectangular aperture through the front 1, near the upper left-hand corner, as seen in Fig. 1, which may be called the reading slot. Near one upper corner is a circular aperture 7, which is the front bearing for the cylinder C of the supplementary bolt controlling device. A rectangular aperture 9 through the side 3 receives a fixed supporting lug, and through a rectangular aperture l() of the side 4 of the case is inserted the separable lug of a supporting plate 20, on which is mounted the counter and the rear bearing 34 forthe cylinder C.

Referring to Fig. 4, two ridges, 11 and 12, a-re cast integrally with the case-front. These constitute ways or guides for a slideplate or closure 13. The slide-plate 13 has a lip 14, extending from the adjacent edge at a right angle. A small hole 15 is made through the slide-plate near the outer end thereof. A projection 16 cast with the casefront l, serves as an abutment or stop to limit the outward movement of the slideplate 13 and there is also an overhanging lip 1Ga to hold the slide plate to the ways.

The case-front 1 has a round bevelededged vdepression 17, across the bottom of which the coin-slot 5 extends diametrically. The two oppositelong edges of the slot 5 are beveled to facilitate the insertion of the coin lthrough said slot to actuate the coincontrolled mechanism. i

In Fig. 4 is shown only so much of the coin-controlled mechanism as communicates movement to the counting-device hereinafter described, which constitutes a portion of my present invention. The part so illustrated is the extreme, upper, free end of a lever 18, pivotally mounted on a proper support (not shown), from which lever a cylindrical stud 19 projects.

The supplementary bolt controlling device, and my automatic closure, with operative connections, which constitute my present invention, are secured in position within the box or case, upon the supporting plate 20. The plate 2O is substantially rectangular in outline and has, at and near one corner, a lip 21, preferably integral with the plate, ex'- tending therefrom at a right angle, the end 22 of which lip is widened, as shown in Figs. 2 and 7.

A block 23, formed with a lug 24, is secured by rivets 25 or otherwise, to the supporting plate 20. This lug is inserted through the slot 9 in the side 3 of the case. Another lug 26 projects from a rectangular block 27, with which it is integral and is attached to the plate 20 by a screw 28.- The block 27, with its lug 26 is thus detachable from the supporting plate 20 at will, whenever the screw 28 is removed.

A shouldered stud 29 is riveted to the supporting plate 20, and on the reduced bearing portion 31 of said stud is mounted the rocker arm 32, which has a notch or yoke slot 33 to engage the counter whereby movement of the said rocker arm causes operation of the counter. This rocker arm is oscillated from the position shown in Fig. 8 in solid lines to the position shown therein by dotted lines (and vice versa) by means of the stud 19 of the lever 18 (Fig. 4), which lever is operated by said coin-controlled mechanism (not shown), the direction of the movement of the stud being indicated in Fig. 8 by the arrows j and g. The two dotted circles marked 19a and 19", and the arrow f show successive positions and the direction of movement of said stud when this mechanism is moved without a coin therein, while the arrow g and the two dotted circles marked 19, 19d, show the direction of movement and successive operative positions of said stud when a coin has been inserted in the said coin controlled mechanism.

The supporting plate 20 is also provided with a circular locking disk 34, supported on a stud or body 35 of substantially smaller diameter (Fig. 8), the stud being riveted, as shown, or otherwise fastened in position on said plate, and the circular disk having a radial slot 36 in its edge. This locking disk constitutes a trunnion or rear bearing for the cylinder of thesupplementary bolt controlling device.

A counter, comprising a series of registering dials 38 or other enumerating members, has a case 39, which is provided with the bracket plates 40, 40, screws 41, 41, secure the counter' by these bracket plates to the supporting plate 20, as illustrated in Figs. 2

and 3. The screws 41, 41, each pass through a cylindrical spacing block 43 (Fig. 2).

On the shaft 44 of the counter is mounted an arm 45, having a split hub 46 whereby said arm is secured to the shaft 44 by a binding screw 47. This arm 45 extends from the shaft 44 and at its free end enters the slot 33 of the rocker arm 32, (Fig. 3) and is oscillated, as indicated in Fig. 8.

The supplementary bolt controlling device comprises a cylinder C mounted by one end in the bearing 7 in the front z' of the lock case, and by the other end on the trunnion or locking disk 34 on the supporting plate 20. Preferably the cylinder is made in two parts, a solid body or plug 8, and a sleeve or barrel 48 in which the plug 8a is secured, as by a pin 49, the projecting portion of the plug 8a serving as a gudgeon or bearing for the cylinder C, to bear and work in the aforesaid bearing 7 of the front plate 1. Tn the plug 8a is formed a keyway with wards to conform to the shape of the key', shown in Fig. 6. The cylinder C is capable of rotation through about 90 degrees, by the key 51, inserted through the key hole 52 in the face of the cylinder, into the keyway aforesaid. Projecting from the cylinder is a cam 67, integral therewith, and whose edge 68 is eccentric to the axis of the cylinder. 'A bolt actuating arm, 69 is also integral with the sleeve 48 and extends therefrom parallel to the cam 67 (Figs. 2 and 5). The bolt actuating arm 69 contacts with a lug 70 of the bolt 71, as shown in Fig. 3, and works the bolt 71 in the guide slot 72 in the side 3 of the case 1 (Fig. 1). Y

Having described the several parts of my invention I will now explain its operation, as applied to the lock of a pay closet or apartment, such as is disclosed in my said Letters Patent No. 1,043,033.

The lock to which my invention applies comprises two bolt controlling devices, one principal and the other supplementary. The principal bolt controlling device is coin operated and is operated by a patron who desires to unlock the door and so gain access to the closet or apartment. He inserts a coin of the proper size and denomination through the coin slot 5. This coin, while it is temporarily in position in the locking mechanism, is itself a member or active element in the combination, so that when the patron manually turns the handle (not shown) of the door, 4he can operate the locking bolt 71 to remove it froml its engagement with the casing of the door or with a catch secured thereto, each coin operated movement of the bolt being recorded by the counter. As explained the dotted circles 19c and 19d show successive positions of the stud 19 of the lever 18 when the principal bolt controlling mechanism is actuated through an inserted coin. The movement of the stud 19 of the lever 18 from the position shown at 19 in Fig. 8 to the position shown at 19c in said figure, causes the said stud to encounter the rocker arm 32 and further movement from 19c to 19d causes an oscillation of the rocker arm 32, upon its pivot 31 from its position shown in solid lines to its position shown in dotted lines. As its slot 33 engages the arm of the counter, each such oscillation causes one depression of the counter arm 45 and consequently advances the counter register one unit. The supplementary bolt controlling device is available to unlock the door of said closet or apartment without the use of a coin for that purpose and without recording the bolt movement on the counter; and it also operates the slide which normally covers, protects and conceals from sight the register of the counter, or permits said register to be exposed at the will of the proprietor who wishes to ascertain how many coins have been inserted in the mechanism to work the same. The supplementary bolt controlling device is operated by inserting the key 51 in the keyhole 52 and turning it in the direction of the arrow z, which action turns the cylinder C and with it the cam 67 and the arm 69. In passing from the position shown in solid lines in Fig. 3, the cam moves away from the inner surface of the lip 14 of the slide plate 13 (Figs. 2 and 3) and when the arm 69 is moved to its extreme position, it

presses the lug 70 of the lock 71, and thereby withdraws said bolt from the door casing or catch as aforesaid. rlhe slide plate 13 is consequently left in its closed position and still'conceals the dials 38 from sight, but by inserting a pin or suitable instrument having a sharp point, into the hole 15 of the slide plate 13, (Fig. 1) the latter can be manually moved to the right (to the position shown by dotted lines in Fig. 3) to uncover the counter register. The difference between the number shown on the dials 38 and the number shown at the last previous reading of the dials indicates the number of coin actuated operations since the last reading, and hence the number of coins that have been inserted in the lock by the patrons thereof. After the dials have been read, the cylinder 6 and its associated parts are turned back by the key 51 from the position in which the cam 67 is shown by` dotted lines in Fig. 3 to the position in which the cam- 67 is shown by solid lines.

In this way the bolt 71 is permitted to return to its former position by action of a spring (not shown), and the cam edge 68 of the cam 67 by its pressure against the lip 14 of the slide plate 13 automatically moves said slide plate from the position shown by dotted lines to its position shown by` full lines in Fig. 3 and so is locked in position.

Without limiting myself to the precise form and arrangement of parts, I claim 1. In a lock apparatus, the combination with its bolt and a lock case having an aperture, of a closure for the said aperture, a member which when moved in one direction acts upon the bolt and releases the closure, and which when moved in the opposite direction acts upon the closure and simultaneously releases the bolt.
